## Overview

This is a small C printf-style formatting library. A caller supplies a format string and variadic arguments; `ft_printf` scans the format, dispatches conversions, and writes formatted output to standard output. Conversion rendering uses the numeric and character helpers in `ft_printf_utils.c`. The graph stays focused on this runtime behavior; the excerpts do not show build configuration or additional product subsystems.

Main entry points: [`printf.c`](https://github.com/kennyohhst/ft_printf/blob/main/printf.c) (Format and dispatch), [`ft_printf.h`](https://github.com/kennyohhst/ft_printf/blob/main/ft_printf.h) (Public declarations), [`ft_printf_utils.c`](https://github.com/kennyohhst/ft_printf/blob/main/ft_printf_utils.c) (Output helpers)

## Components

### Other components

- **Library caller**
- [Public declarations](https://github.com/kennyohhst/ft_printf/blob/main/ft_printf.h): `ft_printf.h`
- [Format and dispatch](https://github.com/kennyohhst/ft_printf/blob/main/printf.c): `printf.c`
- [Output helpers](https://github.com/kennyohhst/ft_printf/blob/main/ft_printf_utils.c): `ft_printf_utils.c`
- **Standard output**

## Connections

- Library caller → Public declarations: uses API (evidence: `ft_printf.h`)
- Public declarations → Format and dispatch: declares (evidence: `ft_printf.h`)
- Format and dispatch → Output helpers: renders conversions (evidence: `printf.c`)
- Format and dispatch → Standard output: writes literals (evidence: `printf.c`)
- Output helpers → Standard output: writes characters (evidence: `ft_printf_utils.c`)
